Title: Improvements in or relating to the Liberation of Hydrogen from Mixtures Containing it.
IPC: C01B3/50
Filed: 1918-04-26
Abstract: 131,091. L'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude. Nov. 17, 1917, [Convention date]. Gases, separating mixtures of. -In extracting hydrogen from gas mixtures by dissolving the other constituents in a solvent under pressure and at a low temperature as described in Specification 130,357, [Class 2 (iii), Dyes &c.] the necessary low temperature is obtained by utilizing, for the direct cooling of the solvent, the cold produced by the expansion in a motor of the gases liberated from the solvent. In the apparatus described, the saturated solvent, in quantities regulated by a slide valve a, is delivered on to the larger face of a differential piston b, the other face of which drives an equal quantity of desaturated liquid towards the dissolving apparatus c, the excess of power developed by the dissolved gases being utilized externally, for instance to drive a fly-wheel v. A second slide valve d regulates the admission of desaturated liquid below the piston b.

Title: Improvements in and relating to milling cutters and similar tools
IPC: B23C5/18
Filed: 1943-05-05
Abstract: 563,108. Milling-cutters &c. FRANCIS, S. May 5, 1943, No. 7112. [Class 83 (iii)] In a milling-cutter or similar tool having a body portion comprising a number of laminµ 10f each provided with a seating to receive the cutting teeth 12e, a central lamina engages a groove 40 in each cutter and acts as a locking plate. All the laminµ have taper holes, those of the central lamina being slightly out of register when the tooth slots are all in alignment so that when the taper pins 43 are inserted the central lamina is rotated slightly to effect the locking. The teeth and the laminae may be additionally secured by brazing, soldering, welding or riveting. In a modification, two assemblies similar to that shown in Fig. 2 are mounted side by side with a spacing plate 10k, Fig. 5, between them which acts as a lateral support for both sets of teeth. The locking plate may have an enlarged key-way slot 16 to permit the rotational movement without obstructing the key-way. Hard metal may be applied to the teeth in any known manner to form cutting-edges.

Title: Improvements in or relating to substituted synthetic linear polymers and their preparation
Inventor: HAAS HOWARD CLYDE
IPC: C08G69/48
Filed: 1955-03-14
Abstract: Fibre-forming and film-forming substituted linear polymers are obtained by reacting a polyamide, polysulphonamide, polycarbamide, polyurethane or an interpolymer thereof with ethylene oxide or ethylene carbonate.  The reaction is preferably carried out in a pressure vessel at 60-110 DEG  C. for 2-60 hours and the polymer may be dissolved in a solvent inert to ethylene oxide, e.g. dioxane, benzene, toluene, hexane carbon tetrachloride and ethylene chlorhydrin, chloroform, ligroin; formic and acetic acids; alcohol/water mixtures; m-cresol.  The reaction may be catalysed by a base, e.g. an alkali-metal hydroxide or a tertiary amine.  In examples: (1) pellets of an interpolymer of caprolactam, hexamethylene adipamide and hexamethylene sebacamide were reacted in a steel bomb with excess ethylene oxide at 78-81 DEG  C. for 15.5 hours; (4) polyhexamethylene adipamide was similarly reacted; (6) caprolactam was reacted with excess ethylene oxide at 78-81 DEG  C.; (7) the reactant was an interpolymer of hexamethylene adipamide and hexamethylene diglycolamide; (8) N - methoxy methylated polyhexamethylene adipamide was treated similarly; (9) as in (8) but the polymer was dissolved in dioxane; (10) the reaction was carried out in presence of aqueous NaOH; (11) a polyamide sulphonamide obtained by interaction of hexamethylene disulphonyl bis-e -aminocaproic acid with hexamethylene diamine was employed; (12) a polycarbamide obtained by reacting tolylene diisocyanate and hexamethylene diamine was reacted with the ethylene oxide dissolved in dioxane; (13) a polyurethane from tolylene diisocyanate and triethylene glycol was reacted with ethylene oxide at 78-80 DEG  C.; (14) an interpolymer from caprolactam, hexamethylene adipamide and hexamethylene sebacamide was reacted with ethylene carbonate in presence of potassium carbonate

Title: Improvements in and relating to a method of fabricating fiber-reinforced articles and products produced thereby
IPC: B29C63/00
Filed: 1968-02-15
Abstract: 1,214,355. Sintered fibre reinforced bodies. UNITED AIRCRAFT CORP. Feb.15, 1968 [Feb.24, 1967], No.7450/68. Heading C7D. In a method of producing sintered fibre reinforced metal bodies, filaments of SiC coated B are overcoated with a matrix metal such as Al, Mg or Ti on their alloys, the volume of overcoating being sufficient to provide the required matrix, and the coated filaments are compacted into the required form and then sintered or alternatively hot pressed. The filaments used have a diameter of 76À2 - 127 microns and a coating 2À54-5À08 microns thick of SiC. They are formed by deposition of B from BCl3 and H2 on to a tungsten wire. SiC is deposited from a gas mixture of methyldichlorosilane, H2 and methane. The matrix metal is deposited by plating, dipping or vapour coating and forms a minimum of 9À3% of the filament area on a cross-sectional basis. The filaments may be packed in a mould e.g. glass tube and compacted and sintered at e.g. 550 -600 C. using an Al matrix. Alternatively they may be wound on a mandrel prior to sintering. The density is controlled by varying the applied pressure and when maximum fibre fill is not needed supplementary matrix metal may be sprayed or infiltrated into the body.

Title: Improvements in the Wrist and Elbow Joints of Artificial Arms.
Inventor: WILSON WILLIAM JAMES
IPC: A61F2/58
Filed: 1917-02-26
Abstract: 113,207. Wilson, W. J., and Markham, F. A. Feb. 26, 1917. Limbs, artificial.-The forearm is raised relatively to the upper arm by means of a cord controlled by the wearer's body movements; this action also causes the elbow joint, and with it the complete forearm, to swicel about the lower end of the upper arm. Simultaneously, the wrist swivels relatively to the lower end of the forearm, and the hand as a whole turns about a hinge joint in the wrist. The operating-cord h, Fig. 2, passes over pulleys j mounted in the upper arm f above and below the swivel joint g, f<1>, the pulleys being normally at an angle on opposite sides of the joint, as indicated in the sectional view, Fig. 4, and the end of the cord is anchored at the ring i to the forearm. Thus when the cord is tensioned, the forearm is raised about the elbow pivot e, and the whole of the parts rotate about the swivel joint g. The initial stress upon the cords rocks a detent lever v, to which the anchoring ring i is attached, so as to withdraw a spring detent v<3> from one of a series of holes w in the elbow joint, the detent re-engaging as the tension ceases. The swivel joint may be locked by a manually operated bolt x in the elbow part of the upper arm, adapted to enter one of a number of holes in the upper arm above the swivel joint. The above-mentioned movements produce a tension in a cord k, anchored in the upper arm at k<1>, and passing over pulleys l, k<3> and down the outer side of the forearm, to a swivel joint b<1>, c<1>, Fig. 8, immediately above the wrist, the cord producing a rotation by means of pulleys m, m<1> as in the case of the upper-arm swivel joint. Finally, the cord passes over a pulley k<4>, mounted upon the hinge-pin a<1> of the wristjoint proper, causing the hand a to turn as a whole inwards simultaneously with the swivelling, and is ultimately secured to and operates a lever mechanism n for moving the fingers of the hand, in opposition to a spring t, which is described in Specification 112,539. The swivel plates f, f<1> and b<1>, c<1> have slots n, Fig. 4, to permit passage of the operating-cords, are provided with ball bearings, and are restored to normal position by springs p coiled around segmental rods q carried by one plate over similarly shaped recesses admitting the projection of apertured lugs s upon the opposite plate so as to work over the segmental rods. The springs bear at one end against the lugs and at the other against the securing-plates r of the rods. The wrist swivel-joint may have a loch similar to that provided for the elbow swivel.
